Variety of sutera plant named &#39;sumsut 06&#39;

ABSTRACT

A new and distinct  Sutera roth  plant named ‘Sumsut 06’ with white colored double flowers and a hanging growth habit.

BOTANICAL CLASSIFICATION

Sutera roth

VARIETAL DENOMINATION

‘Sumsut 06’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Sutera plant known by the varietal name ‘Sumsut 06’. The new variety was discovered in June of 2005 in a selected breeding program in 's Gravenzande, The Netherlands. The purpose of the breeding program was to develop double-flowering Sutera plants with large flowers. The new variety is a selection from the cross of proprietary, unpatented breeding plants. The female parent was Seedling 1-5 and the male parent was Seedling 2-34. The double-flowering characteristic of the new variety is similar to its parents, but the new variety exhibits a different flower color and larger flowers when compared to both parents. The new variety was first asexually reproduced in September of 2005 by tip cuttings in 's Gravenzande, The Netherlands. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remains true to type through successive asexual propagations.

The following traits distinguish ‘Sumsut 06’ as a new and distinct cultivar from other Sutera varieties known to the breeder.

-   -   Big and double flowers;     -   Hanging growth habit; and     -   Three stigmas per flower.

The new variety exhibits double flowers like Sutera variety ‘Sumsut 05’ (U.S. Plant patent application Ser. No. 12/284,404, applied for concurrently). However, ‘Sumsut 06’ has white flowers and a hanging growth habit, while ‘Sumsut 05’ has violet flowers and a compact growth habit. The following Table 1 provides a comparative listing of botanical characteristics of ‘Sumsut 06’ and ‘Sumsut 05’.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is a photograph of an entire plant of the new variety; and

FIG. 2 is a close-up photograph of the flowers of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out in The Netherlands. The new variety was grown outside in a 37 cm container and was 20 weeks old when described. The color readings were taken indoors under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
